PRINTING-.PRESS.

SPECIFICATION forming part of Letters Patent No. 593,164, dated November2, 1897. Application filed October 28, 1896. Serial No. $1 0,356. (Nomodel.)

To all whom, zit may concern:

Be it known that I, FRANK A. PULHEMUS, a citizen of the United States,residing at Hopkins Station, in the county of Allegan and State ofMichigan, have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification. 7

My invention-relates toimprovements in bed and cylinder presses; and itsobjects are, first, to provide a light,-easyrunning, and convenientcylinder-press that may be conveniently run by hand-power, and, second,to provide means to prevent the cylinder from pressing upon the nakedtype when passing back over the form after having discharged the printedpaper. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a side elevation of mypress. Fig. 2 is a plan of the same with the paperstand removed to showthe inking-rolls and table. Fig. 3 is a plan of the adj ust-ing-shaftand eccentrics; and Fig. t is a sectional end view of the cylinderresting on the top rail of the frame, illustrating the manner ofactuating the fingers that secure the paper to the cylinder.

Similar letters refer to similar parts th roughont the several views.

My press is mounted upon a supportingframe A, and at each side of thisframe I pivot a toothed track B to the plate, as atb. The opposite endsof these tracks are supported on the eccentrics j, said eccentrics beingmounted on the shaft J 2 in such a manner that when the cylinder 0 iscarried to the position indicated at 0' its rim 0 comes in conwith thegear-teeth on the tracks B, so that the cylinder cannot be made todeviate from its proper course or position and the fingers 0 will alwaysbe in the proper position when the cylinder is at c" or the positionshown in Fig. 2 to receive the paper from the paperstand I and place itproperly on the form E for printing. Outside of these gear-wheels, ateach end, I place a flange 0, which acts a double purpose-first, toengage with the levers H, J, and J in the manner and for the purposehereinafter more fully set forth, and,

second, to act as a convenient handhold with which to nfanipulate thecylinder. The lever J is connectedto the lever J by the connecting-rod jin suchamanner that the flange C of the cylinder when passing from c to0 will throw the lever J to the position shown in Fig. 1 and with it thelever J to its corresponding position, as shown by the solid lines insaid figure, and by this means carry the eccentrics froinunder thetracks B, so that the return of the cylinder will be so close to thesurface of the typeform E as to insure a perfect imprint of the type onthe paper.

My appliance for operating the fly F con-' sists of the gear-wheelsG'and G, so arranged that the turning of the wheel G will turn the wheelG and throw the fly to the positions necessary to receive the papersfrom the cylinder and deposit them on the receiving-table. This actionis achieved by the use of the lever H, whichis connected with the arm 9on the wheel G by means of the connectingrod h. The lever H is pivotednear its longitudinal center to the frame A, and the connecting-rod h isattached below this point, so that the motion of the upper end of thelever is transmitted to the arm g in the reverse direction. concave TarmII in position so that the flange of the cylinder 0 when passing over itwill throw it in the direction that the cylinder is moving, so that whenthe cylinder is moving toward a the lever will be carried over to theposition indicated by the dotted lines and the fly is thrown to theposition indicated by its dotted lines in Figs. 1 and 2 just in time topass the cylinder and receive the paper as it At the upper end of thelever I form a cylinder or cylinder shaft somewhat as indicated in Figs.1 and 2 by connecting-rods so that they will be actuated by themovements of the cylinder to pass from the inking-pad K to theprinting-form E, and vice versa.

The fingers c are actuated by any ordinary device that may be madeavailable for the purpose-as, for instance, the lever c in passing overthe beads a upon the top rail of the frame. (See Fig. 4.)

The paper-stand I may be supported on standards 2'.

P represents the paper passing to the cylinder, and h is a stop for thelever H.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent of the United States, is

1. In a printing-press, a supporting-frame, a track pivoted at one endto one end of each side of the supporting-frame, a shaft. having aneccentric at each end in position to actuate the free end of the tracksvertically, a lever attached to said shaft in position to be actuated bythe cylinder, a lever at the, other end of themachine connected withsaid lever and in position to be similarly actuated by the cylinder butin the opposite direction, a lever pivoted to the side of the frame, aT- ar-m across the top of said lever in position to be actuated by theflange of the cylinder in either direction, a connecting-rod passingfrom said lever to a gear-Wheel at the foot of the press, a small gearmeshing with said gear, a fly secured to the shaft supporting said smallgear so that the motion of the lever is utilized to actuate the fly toand from the cylinder, a cylinder arranged to actuate the severallevers, to receive, print and discharge papers and inking appliancesconnectt ed to act with said cylinder, substantially as and for thepurpose set forth. 2. The combination, with a frame, an impressioncylinder, a form and adjustable carrying-tracks; of a fly pivoted at oneend of the frame, a gear and rack attached to actuate said fly, and alever centrally pivoted to the frame, a T at its upper end in positionto receive the moving cylinder and transmit its motion to the lower endin a reverse direction and thence, by means of a connecting-rod toactuate the fly gear and rack, substantially as and for the purpose setforth.
